I too prefer a more controlled scrappy. In my case I like to have a single unifying color or group fabrics in like color families. My preference is to add some order to the chaos that can happen with no holds barred scrappy.
While I do like a lot of Kaffe's fabrics I have none in my stash and probably won't buy any because I do find his scales hard to work with. Sometimes I like quilts made with his fabrics, sometimes they do nothing to float my boat.
I wouldn't call your quilt a disaster but if it is not your cup of tea that certainly puts a damper on your enthusiasm to continue and I have definitely been there too, only to completely finish the quilt and still hate it. So you are wise to recognize that before spending any more time and effort on something you don't like at all.
